\(C_{1,{A}}\) SM=-If3,2\(\sin \theta _{}\cos \theta _{}\) = -0.6012 (14),

where \(\theta _{}\)  is the Weinberg angle,
and \(Q_\mathrm {f}\)  and \(I^\mathrm {f}_{3,}\)  label the charge and the third component of the isospin of the SM fermions, respectively [1]}.
The dipole moments, moreover, are generated only radiatively in the SM.
Their small numerical values, which are well below \(10^{-3}\)  [2]}, [3]}, [4]}, therefore allow stringent tests of the SM.
Beyond \(()\) , several observables have been considered that are sensitive to anomalous electroweak interactions of the top quark [5]}.
Among them, \(\cos \theta ^\ast _{} \)  has a high experimental resolution and provides the best discriminating power when compared to a comprehensive set of alternative choices calculated using the reconstructed leptons, jets, and -tagged jets.
